Hi William,

Changing the 15ms timer will not be a viable solution for two reasons. Number 1: it will still split the input into several undo commands because the timer will eventually run out. Number 2: increasing the timer interval will negatively affect the user experience while typing - nothing will be inserted in the document until the time has elapsed.

I have made several videos demonstrating the default behavior (15ms), when the timer is set to 500ms, and when it is set to 1000ms. In every case, I will start typing by pressing a letter on the keyboard and never letting it go to simulate a constant input.

As a side note, currently, you can still update the timer's interval by using a custom Caret class and setting this in its constructor:

this.MinimumTextInsertedInterval = 500; // The time buffer in milliseconds.

Afterward, to hook the new caret you will need to follow the instruction from this article - How to implement your own IME support? But be wary that, as discussed earlier, this will deteriorate the typing experience.

The correct approach would be to internally merge the two neighboring undo steps of type "Typing" into one when some external requirements are met.

We have already finished the planning process for the current release cycle. I can not promise when this feature will be implemented. So, be sure to subscribe to this item, to receive updates when its status changes.
